COMPENSATING SPRING FOR WIRE FENCES.

SPECIFICATION forming part of Letters Patent N0. 760,513, dated May 24, 1904. I Application filed October 23, 1903. Serial No. 178,170. (No model.)

To all whom it may concern:

Be it known that I, ALEoED E. BAILEY, a citizen of the United States, residing in In dependence township, (post oflice address Clarkston,) in the county of Oakland, State of Michigan, haveinvented certain new and useful Improvements in Compensating Springs for Wire Fences; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a compensating spring for wire fences; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

I The object of the invention is to provide a compensating spring for wire fences, wherein the arrangement is such as to permit of the expansion and contraction of said wires without deleterious effect and at the same time maintain a proper tension upon the fence.

The above object is attained by the structure illustrated in the accompanying drawings, in which- Figure 1 is a plan view of the device embodying my invention. Fig. 2 is an elevation in detail showing the application of my invention. Fig. 3 is atransverse section as online 3 3 of Fig. 1. Fig. 4: is a perspective View of the device.

Referring to the characters of reference, 1 designates a metal yoke having parallel side portions 2, whose ends are provided with ears 3, that are folded inwardly to form embracingways, in which the parallel side pieces 4 of the yoke 5 are adapted to slide, said yokes being thereby united in a manner to form a rectangular telescopic frame. Passing through the ends of said yokes is a tie-bolt 6, having a nut 7 upon each end thereof. Surrounding said bolt and confined between the ends of the frame formed by said yokes is a compressible spring 8. The telescopic frame and its compressible spring are adapted to form a complementary portion of the line-wires 9 of the fence. For the purpose of attaching said wires to the frame a loop 10 is formed on the end of each of said wires, which passes freely through the slots 15 in the end of the yoke l and is looped through the slots 16 in the end. of yoke 5, as shown at 11, whereby any stress which may be placed upon said wire is borne by said yoke 5.

For the purpose of attaching the device to a post a wire 12 is employed, which is secured to the post 13 in any suitable manner and is provided with a loop 14, which passes freely through the slots 16 in the end of yoke 5 and is looped through the slots 15 in the end of yoke 1, whereby theresisting force of the loop 14: is applied to yoke 1. By means of this arrangement it will be seen that any strain applied to the longitudinal wire 9 will operate to cause the parts of the yoke to slide together, which movement is resisted by the interposed spring 8 until the strain upon said wires is suflicient to overcome said spring, when the parts of the yoke or frame will telescope or slide together until the force of the spring equals the strain upon the wire. As the strain upon the wire slackens the spring 8 will expand and take up the slack thereof.

It will now be understood that by means of this device a compensating spring is provided which allows for the expansion and contrae tion of the fence-wiro and at the same time maintains said wire taut.

Any desired tension may be placed upon the line-wire by screwing the nuts 7 upon the ends of the tie-bolt 6, so as to contract the telescopic frame and compress the spring 8.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device for the purpose set forth, the combination of the telescopic frame, the tiebolt passing through the opposite movable parts of said frame, the compensating spring upon said bolt and the wires passing freely through the end of the frame and engaging the opposite end thereof.

2. In a compensating spring for wire fences, the combination of the frame composed of the yokes whose sides are slidably united, the bolt passing through the ends of said yokes, a compressible spring upon said bolt confined between said ends and the wires attached to opposite ends of the frame in opposed relation.

3. In a compensating spring for wire fences, the combination of the angular yokes united to allow them to slide one upon the other, a compressible spring interposed between the ends of said yokes, means for regulating the tension upon said spring, the ends of the yokes having apertures therein, attaching wires passing freely through said apertures at one end, and engaging the yoke at the opposite end in opposed relation.

In testimony whereof I sign this specification in the presence of two witnesses.
